The Theory And Practice Of Formative Assessment Based On Learning Activities In Blended Learning Environment

Along with the promulgation of"Educational Technology Ability Standards for Primary and Secondary School Teachers", the training of the educational technology ability of primary and secondary teachers has now become a widespread concern. As the training projects have been gradually carried out among the country, how to monitor the quality of the training, how to evaluate the trainees'performance effectively has become an urgent problem.Along with the advent of the information age, learning environment, learning mode is enduring a tremendous change. How to make use of the advantages of information technology to monitor the quality of the training, evaluate the trainees'learning process, is the focus of the research in teacher education and teachers'training in information technology environment.Based on the "national teacher education and technology capacity building for primary and secondary schools" projects, the study is carrying out in terms of the formative assessment theories, modes and implement in technical supported environment. In the blending learning environment, the formative assessment system, which is based on the learning activities, can guarantee the high-quality learning of the trainees. In the condition of trainees'active participation, the system would be able to stimulate, assist, improve trainees'learning, enhance the trainees'educational technology capacity, and guarantee the projects'quality and promote their healthy development.The study starts from the characteristics of teachers'educational technology capacity and training standards outline, demonstrates the training's unique characteristics which are different from previous training, establishes the relationship between activities, evaluation, and capacities. Combined with specific training activities, the study analyzes two sets of teaching materials (the Higher Education Edition and NTNU Edition). Especially the innovative training model and blending training concept of Higher Education Edition provides research condition for the formative assessment system based on the Web-based system. Specifically:(1) Summarizing and analyzing the classification and meaning of learning activities in blending learning environment. The study classifies learning activities types in blending learning environment, based on the activities entities'sociability (class activities, group activities, individual activities), and demonstrates that blending training mode and well-designed, organized network training are the optimal training mode in information technology environment, based on the quantity and characteristics of activities'types.(2) The establishment of the training mode and evaluation mode of blending mode. Based on the Educational Technology Learning Circle (ETLC) theory and Educational Technology Learning Flow (ETLF) model, we established Educational Technology Evaluation Model (ETEM) in blending learning environment, and proposed the Educational Technology Training Mode (ETTM) based on ETEM. ETTM not only provided the theoretical mode for TETA project, laid the foundation for the success of the project, but provided valuable experience for other training projects.(3) The establishment of the indicators system for formative assessment. We researched on the establishment of evaluation index, the index weight, and data calculation. In the research, we applied AHP and the ideas of fuzzy mathematics into the establishment of the evaluation index for educational training evaluation system for the first time. We established a set of scientific, universal formative assessment index system to ensure that the formative evaluation index system used in the project is scientific, as well as providing a model for other training projects which are based on the process of the formative assessment system.(4) The design and implement of the formative assessment system which is firstly large-scale used in China, based on the evaluation model and evaluation index system. The system provides full support for the quality monitor and the need of formative assessment of primary and secondary teachers'educational technology ability building projects. The system not only records, analyzes, and provides feedback for the trainees'learning process, but monitors and provides feedback for the entire training organization. It will become the core of network instructional evaluation gradually.
